The below information is for reference only. We will continue to evaluate and adapt to changing COVID-19 guidance and adjust operations as needed.

The National Park Service is working service-wide with federal, state, and local public health authorities to closely monitor the COVID-19 pandemic. Based on guidance from the Centers for Disease Control and Prevention (CDC), and state and local public health authorities, access to Mammoth Cave National Park includes: cave tours; the park visitor center; campgrounds; hiking, biking and equestrian use trails; waterways; roads; and in-park concessions operations such as lodging, food and beverage, and retail.

While these areas are accessible for visitors to enjoy, a return to full cave tour operations will continue to be phased. Future tour schedules will be released as soon as optimal tour options are determined in accordance to CDC and public health guidance.

Park visitors are required to wear masks indoors. Masks are required for everyone on all forms of public transportation including bus transportation for cave tours and while on cave tours. Additional details are available at www.nps.gov/coronavirus.

We ask our visitors to recreate responsibly and follow CDC guidance to reduce the spread of COVID-19, including staying home when feeling sick.
